COLD-STORAGE APPARATUS.

Specification of Letters Patent.

Patented April 23, 1907.

Application tiled September 20, 1906. Serial No. 335,462.

To ctZZ whom, it may COMO/3TH.

Be it known that we, NATImN II. DEVERS and EDWARD WILLLmis, citizens ofthe United States, residing at Vl ashington, in the District ofColumbia, have invented certain new and useful Improvements in Cold-Storage Apparatus, of which the following is a specification, referencebeing had therein to the accompanying drawings.

This invention relates to improvements in cold storage apparatus, andthe main object of the invention, is the provision of a casing embodyingan ice storage compartment, preferably above the storage compartment, aseries of conduits bein so provided as to allow the cooled or colc airto descend into the storage compartment, at equal distances around thesides of the storage compartment.

The present apparatus is designed for the cold storage of beer or otheraerated liquids, and also for refrigerating meats and the like, theapparatus being a built-up structure adapted to be built in any desiredor convenient place; and maybe of any size or proportion, according tothe purpose for which the apparatus is intended.

To attain these objects, the present invention consists of a coldstorage apparatus, embodying novel features of construction andcombination of parts, substantially as disclosed herein.

In the accompanying drawings,Figure 1 1s a transverse vertical sectionalview of a complete apparatus. Fig. 2 is a similar view taken on line wacFig. 1. Fig. 3 is a detail view showing storage for beer kegs, and Fig.4 is a detail view of the trap.

Referring to the dra'wings,-the numeral 1 designates footers or concretebase, which is preferably below the frost line, and carries the concretefloor 2, which inclines slightly to one side. Supported upon this flooris the apparatus, which consists of the usual four walls, each of whichis formed of vertical layer of hollow terra-cotta tiles or pipes 3,faced with a layer of cement topping or smooth tile 4, and another outerlayer 5, of tiles or pipes, which provide a space 6, filled With afilling of crushed or pulverized cork 6, or other insulating material.Upon the outer face of the tiles or pipes 5, is placed a solid wall 7,which may be of any desired material, preferably a glazed or vitreoustile. The top 8, is composed of the inside layer 9,

of tile or cement topping, while the series of hollow rerra-cotta tilesor pipes 10, are held in place and supported by the cement con- CI'OLOgirders 1.1, the whole being covered by cinder cement concrete 12, andcement topping 13.

Dividing the (it sing into an upper .ice compartment l t, and a lowercold storage conipartnient 15, is a concrete partition or lloor 16,having a cement topping 17, which inclines toward the same side as thelloor. In order to carry off the waste from the upper compartment, adrain 18, having an iron grating strainer is provided in the lloor 16,while a similar drain 19, is provided in the lloor 2. These drains areconnected to the drain pipes 20 and 20, by means of the removable glasstraps 21., the construction of which is clearly shown in Fig. 4. By thismeans the sediment is readily observed and the entire trap removed andcleaned. In order that the cold air will enter the lower compartment andbe so disposed as to evenly distribute the same throughout the entirelower compartment, the four series of pipes or conduits 22, one seriesmounted in each wall, are provided. The mouths of these pipes enter therespective compartments above and. below the floor 16, and the distanceabove or below may be regulated accordingly as the cold air may bedesired.

In each compartment is provided a door 23 and 2 1, which may be of anydesired construction, and either swing or slide, as occasion requireswithout departing from the spirit of the invention.

As clearly shown in .Fig. 3, the waste drain water from the uppercompartment is used to cool kegs of beer, the waste water being conveyedto the tank 25, which is so constructed as to contain the water and thekegs, a hoisting apparatus 26, being employed to facilitate the handlingof the kegs.

The pipes or conduits 22, are preferably made of a vitreous material, soas not to corrode, that is they may either be made of vitreous linedterra-cotta or of glass, and the main portion of these pipes are mountedin the space 6, and surrounded by the cork filling 6 \Vhat is claimedand desired to be secured by Letters Patent, is,

1. In a cold storage apparatus, the combination of a casing, the wallsof which are made of two layers of hollow tile separated by a spaceextending from the bottom to the top of the casing, a filling of heatinsulation within said space, a partition dividing the easin into anupper and a lower compartment, and conduits permitting communicationbetween the compartments located in the space between the layers of tileequidistant apart around the wall, and having their ends projectingthrough the inner layer of tile into the casing above and below thepartition, for the purpose set forth.

2. In a built-up cold storage apparatus, the combination of footersadapted to project below the surface, a casing having a concrete floorand a concrete top mounted thereon, and consisting of front, rear andside walls made each of two layers of hollow earthen tile separated by aspace extending from the floor to the top, a filling of heat in sulationwithin said space, a concrete partition supported by the walls andseparating the casing into an upper and a lower compartment, andconduits permitting communication between the compartments located inthe space between the layers of tile in the walls, and each having theirtwo open ends projecting through the inner layer of tile into the casingabove and below, respectively, the partition, for the purpose set forth.

In testimony whereof I aflix my signature in presence of two witnesses.
